[0016] The following further describes the present utility model in detail with reference to the drawings.

[0017] Embodiment: A globe valve cleaning device, as Figure 1As shown in the figure, it includes a cleaning machine base 1, on which a valve body conveying component and a valve body cleaning component are movably connected. After the processing personnel complete the processing of the valves, the valve bodies to be cleaned are sequentially fixed on the valve body conveying component for processing and then conveyed to the valve body cleaning component for cleaning and processing.

[0018] As Figure 1 and Figure 2 shown, the valve body conveying component includes a valve body conveying block 2 slidably connected to the cleaning machine base 1 and a driving air cylinder 5 fixed on the cleaning machine base 1 to drive the movement of the valve body conveying block 2. A guide rail groove 6 for the sliding of the conveying block valve is provided on the cleaning machine base 1, and the driving air cylinder 5 drives the valve body conveying block 2 to move along the guide rail groove 6. The valve body conveying block 2 includes a conveying block one 3 and a conveying block two 4, which can effectively improve the efficiency of the valve cleaning process. The conveying block one 3 and the conveying block two 4 work at intervals to ensure the rapid conveying and output of the valves to be cleaned. In order to further improve the smoothness and reliability of the conveying process of the valve body conveying block 2, limiting guide grooves 21 are provided on both sides of the bottom of the guide rail groove 6, and limiting guide blocks 22 cooperating with the limiting guide grooves 21 are respectively provided on the conveying block one 3 and the conveying block two 4, which improves the conveying stability and limiting deviation correction of the valve body conveying block 2.

[0019] A plurality of valve body positioning slots 8 are provided on the valve body conveying block 2. The processing personnel clamp one end of the valve to be cleaned and processed in the valve body positioning slots 8 to achieve fixation. At the same time, a water outlet cavity 9 is provided at the bottom of the valve body conveying block 2, and a water outlet hole 10 communicating with the water outlet cavity 9 is provided at the bottom of the valve body positioning slot 8. A pair of flow discharge baffles 11 are movably connected in the water outlet cavity 9. Rotating shafts 12 rotatably connected to the cavity wall of the water outlet cavity 9 are provided at both ends of the flow discharge baffles 11, and the flow discharge baffles 11 remain closed in the non-cleaning state.

[0020] As Figure 1 , Figure 2 and Figure 3 shown, when the valve body conveying block 2 conveys a plurality of valves to a specified position under the action of the driving air cylinder 5, the valve body cleaning component cooperates to work. The valve body cleaning component includes a pneumatic lifting base 13 fixed to the cleaning machine base 1 and a valve body cleaning cavity block 14 that is liftably and slidably matched with the pneumatic lifting base 13, and the valve body cleaning cavity block 14 moves vertically. An opening 15 is provided at the bottom of the valve body cleaning cavity block 14, and a step block 26 cooperating with the opening 15 is provided at the top of the valve body conveying block 2. That is, when the step block 26 on the valve body conveying block 2 is hermetically engaged with the opening 15, the cleaning of the valves is started inside the valve body cleaning cavity block 14 to ensure the efficient cleaning of the valves on the valve body conveying block 2. After the cleaning is completed, the valve body cleaning cavity block 14 is lifted under the drive of the pneumatic lifting base 13 to facilitate the sliding out of the valve body conveying block 2.

[0021] On the inner side wall of the cavity of the valve body cleaning cavity block 14, there are multiple rotating brush rollers 16, which can clean the surface of the valve to be cleaned. On the surface of the valve body conveying block 2, there are screen holes 27, and the surface impurities brushed off accumulate in part of the screen holes 27 and are synchronously discharged through part of the water outlet cavity 9.

[0022] At the top end inside the cavity of the valve body cleaning cavity block 14, there are also multiple cleaning spray nozzles 17. After the valve body cleaning cavity block 14 moves down to complete, keep the part of the cleaning spray nozzle 17 inserted into the end of the valve away from the valve body positioning slot 8. At the top end of the valve body cleaning cavity block 14, there is a water supply hose 25 connected to the cleaning spray nozzle 17, and the inner cavity of the valve is flushed by the water spray scouring through the part of the cleaning spray nozzle 17 inserted into the valve cavity; there is also a high-pressure air flow punch 23 on the cleaning spray nozzle 17, and at the top end of the valve body cleaning cavity block 14, there is a high-pressure air pipe 24 connected to the high-pressure air flow punch 23, and the reliable cleaning and drying effects of the inner cavity of the valve are achieved by adopting the intermittent combined working mode of water spray and air flushing.

At the end of the rotating shaft 12 of the flow discharge baffle 11, there are transmission gear blocks 19 that cooperate with the rack block. On the valve body conveying block 2 above the transmission gear block 19, there is an auxiliary positioning groove 20 for the linkage rack block 18 to be movably inserted. That is, when the valve body cleaning cavity block 14 moves down driven by the pneumatic lifting base 13, the linkage rack block 18 is inserted into the auxiliary positioning groove 20. It can not only achieve the deviation correction and positioning between the valve body cleaning cavity block 14 and the valve body conveying block 2, but also drive the opening of a pair of flow discharge baffles 11 through the mutual transmission between the two side transmission gear blocks 19 and the linkage rack block 18, so as to discharge the impurity wastewater discharged along the water outlet holes 10 and the screen holes 27 from the water outlet cavity 9. There is a flow discharge groove 7 at the bottom of the guide rail groove 6, and finally the impurities and sewage discharged from the water outlet cavity 9 are converged through the flow discharge groove 7 for recycling, forming a reliable and efficient valve cleaning and processing system.
